http://bugzilla.opensuse.org/show_bug.cgi?id=1180543 Bug ID: 1180543 Summary: kernel 5.10.4: Displays never wake up, though on one system it does... network is also dead Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.2 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: manfred.h@gmx.net QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Hi there, this is more like a heads up for everyone. I installed kernel 5.10.4 when it became available in Kernel:stable, so around 12:00 hrs CET at Jan 1st. I have since then had issues with three of my systems which never occured to me so far. The issue is, that there is no display anymore after some time (>= 20 minutes) (i.e. switching to another vtty doesn't work), and the network also doesn't work. Interestingly, one system (a Dell Latitude 5500 with an Intel Core(TM) i5-8365U CPU) still works OK. Common to all systems is the following: - openSUSE Leap 15.2 with all updates - builtin Intel graphics, no external graphics card - builtin Intel network card What's different is the graphics connector: - HDMI on two systems - DisplayPort on one system The Dell laptop - which works OK - is using its builtin display, so no HDMI or DisplayPort. I can only use the usual Ctrl-Alt-Print-... sequences to get them cleanly shut down and reboot. This never happened with any kernel from Kernel:stable up to 5.10.3! I'll be off for two days, but thought this might be interesting for other users/developers here. I tried both options for kernel-firmware: - 20200107-lp152.2.3.1 (from Leap 15.2 Updates) - 20201218-35.1 (from Kernel:stable) without any difference - which makes me believe that this is a kernel related issue. -- You are receiving this mail because: You are the assignee for the bug.
